摘要： Polycarbonates containing low or undetectable levels of Fries rearrangement products and comprising repeat units derived from one or more of resorcinol, hydroquinone, methylhydroquinone, bisphenol A, and 4,4′-biphenol have been prepared by the melt reaction of one or more of the aforementioned dihydroxy aromatic compounds with an ester-substituted diaryl carbonate such as bis-methyl salicyl carbonate. Low, or in many instances undetectable, levels of Fries rearrangement products are found in the product polycarbonates obtained as the combined result of a highly effective catalyst system which suppresses the Fries reaction and the use of lower melt polymerization temperatures relative to temperatures required for the analogous polymerization reactions using diphenyl carbonate.

摘要： Stable, homogeneous melt solutions are prepared at temperatures of 200° C. or less from solid mixtures comprising at least one diaryl carbonate, at least one high melting dihydroxy aromatic compound (mp>200° C.), a transesterification catalyst, and optionally a lower melting dihydroxy aromatic compound. Thus, a stable, homogeneous melt solution is obtained from a solid mixture comprising 4,4′-biphenol (mp 282-284° C.) at a temperature of about 200° C. using either diphenyl carbonate or bis(methyl salicyl) carbonate as the diaryl carbonate component. It is shown that formation of the stable, homogeneous melt solutions requires the presence of the transesterification catalyst when substantial amounts of the high melting dihydroxy aromatic compound are present in the initial solid mixture. Solid mixtures comprising a variety of high melting bisphenols; 4,4′-biphenol; 3,3,3,3′-tetramethylspirobiindanbisphenol, and 4,4′-sulfonyidiphenol are converted to stable, homogeneous melt solutions at 200° C., a temperature substantially below the melting points of the high melting bisphenols in their pure states.

摘要： This invention relates to an extrusion method preparing polycarbonates from a solution of an oligomeric polycarbonate. A mixture of bis(methyl salicyl)carbonate (BMSC), BPA and a transesterification catalyst are first equilibrated at moderate temperatures to provide a solution of polycarbonate oligomer in methyl salicylate. The solution is then fed to a devolatilizing extruder, where the polymerization reaction is completed and the methyl salicylate solvent is removed. The solution comprising the oligomeric polycarbonate can also be pre-heated under pressure to a temperature above the boiling point of methyl salicylate and subsequently fed to a devolatilizing extruder equipped for rapid flashing off the solvent. The method provides polycarbonate with greater efficiency than the corresponding process in which unreacted monomers are fed to the extruder. Additionally, the method of the invention does not require the isolation of a precursor polycarbonate comprising ester-substituted phenoxy terminal groups.

摘要： A solar array system includes a plurality of power-generator modules, each power-generator module having an identical form factor and comprising a plurality of photovoltaic cells wired for power generation. The system also includes at least one sensor module having a substantially identical appearance and form factor as the power-generator modules and comprising a like plurality of photovoltaic cells. The operational state of the system is monitored by an array performance monitor, which measures signals sent from the various modules. At least one photovoltaic cell in the sensor module delivers a short-circuit current signal to the array performance monitor and at least one photovoltaic cell in the sensor module delivers an open-circuit voltage signal to the array performance monitor. These signals are used to calculate a theoretical power output of the array system, which is compared to the actual power output.
